Boat holiday in Northern Germany in summer 2026

Which nice lady fancies a boat trip in Northern Germany; (Berlin), Hamburg, Elbe, Elbe-Lübeck Canal, Baltic Sea, Kiel Canal, Elbe, Hamburg, (Berlin), on a motorboat, in summer 2026, date negotiable or by arrangement or depending on good, sunny weather, planned as a stress-free time on the water. Duration of the trip by arrangement and/or according to shared enjoyment, approximately between six and ten days. Some overnight stays on the boat and some in hotels or similar are planned, depending on mood. The lady traveling with us only needs to contribute a good mood and her swimsuit. I think a prior meeting over coffee is in our mutual interest. A reply with a picture will be answered in any case.
